摘要： One example method includes varying oil injection by an oil injector onto a piston of an engine to accommodate different operating conditions. For example, by adjusting oil injection, suitable cooling effects can be provided without providing additional oil that increases the amount of oil deposits in the engine. In this way, the risk of pre-ignition can be reduced.

摘要： Embodiments for indicating degradation of a piston-cooling jet system are provided. In one example, an engine method comprises indicating degradation of a piston-cooling jet system in response to a relationship between engine speed and oil pressure at maximum oil pump displacement conditions. In this way, engine operation may be adjusted in response to an indicated degradation.

摘要： Systems and methods are disclosed for adjusting oil pressure supplied to engine components. In one example approach, a method for controlling oil flow in an engine comprises adjusting oil pressure supplied to the engine based on engine acceleration. For example, engine acceleration may be used to predict future engine lubrication requirements so that oil pressure adjustments may be scheduled accordingly.

摘要： Methods and systems are provided for controlling exhaust emissions by adjusting a fuel injection into an engine cylinder from a plurality of fuel injectors based on the fuel type of the injected fuel and further based on the soot load of the engine. Soot generated from direct fuel injection is reduced by decreasing an amount of direct injection into a cylinder as the engine soot load increases.

摘要： Systems and methods for modifying oil pressure for a variable cam timing system are provided. In one example approach, a method comprises, in response to an operating condition, adjusting a valve coupled to a hydraulic variable camshaft timing actuator to initiate camshaft phasing and adjusting an oil pressure supplied to the valve based on a camshaft phaser position. If a camshaft phaser locking pin is in a home position, the method may further comprise reducing the oil pressure supplied to the valve for a predetermined time interval to a threshold amount to unlock the locking pin but not move the camshaft phaser and then increasing the oil pressure supplied to the valve to move the camshaft phaser.
